Loading Data Files into N7

[gp123]

I'd like to manually move (not sync) some music files/folders from Win7 desktop PC to a newly created folder on N7.
Can mount N7 as a HD on my PC via USB and see its file system.  Can add this new folder to the N7 structure -- but where ??  In what directory??

Once I do this I assume that I can copy (drag and drop) desired data files/folders into this newly created folder.  Right?

The new folder will contain music tracks in wma format. Purpose of all of this is to have a wma music player on N7 (WinAmp is the only one I've found) play the contents of this new folder.  Is it better to associate folder/files with the WinAmp player, or to have the player simply search for wma files on N7 -- where ever they may be?

Most people put their music files in a /Music folder but it doesn't matter as the media scanner will find them anywhere.
